[ale] Weird SCSI Drive Compatibility Issue

[Klepinger, Aaron]

Firmware is the first thing I check on old hardware.  The older firmware is
usally fairly rotten.  I agree with what some others have said and I'd
update firmware first thing.

I let the 2940UW controller run a verify on the drive and sure enough,
it acted as though the drive were really 31MB.  I shut down and moved
the cable from the 2940UW to the Initio card I'd put in, and its BIOS
reports 4.2GB as it should.  I'm letting the Initio card do the format
as I type to see if that makes any difference.  

I may find myself looking at needing to pick up a proper UW drive and
cable.  Still, I wish I understood what was going wrong.

I probably should point out that under the Gentoo install, I did attempt
to go ahead and fdisk the putative 31MB drive to create a partition, but
subsequent attempts to do things like mke2fs /dev/sdb1 met with failure,
as though there were no sdb1.
